ROAD WORKCHPTER THREE

Page 20: Presentation sayed

Road is an important aspect in development of certain area, it provide linkage between area to another area and hence improve the social growth to an area.

Road Work---Introduction:

Page 21: Presentation sayed

The location of a road and its design are considerably influenced by the topography, physical features, and land use of the area traversed. The topography of the profile of a road can generally be divided into three groups, namely flat, rolling and mountainous.

Road Work---Introduction:

Type Description

Flat terrain

The natural ground cross slopes in a flat terrain are generally below 3%

Rolling terrainThe natural ground cross slopes in a rolling terrain are

generally between 3 – 25%

Mountainous terrain

The natural ground slopes in a mountainous terrain are

generally above 25%

Page 22: Presentation sayed

To propose the vertical and horizontal alignment of the service road.

To design the flexible pavement thickness for each layer of the pavement structure.

To propose safe and convenient route of road user by complying with all technical Requirements.

Road Work---Objectives:

Page 23: Presentation sayed

The critical point of any road pavement design is the commercial vehicle which is considering the main parameter of designing

In our area the volume of commercial vehicle per day is too low, so that’s why we used the JKR new standard for the low volume of commercial vehicle, thus assuming that a the surrounding area will be developed in the early future so we design the main road by assuming a higher amount of commercial vehicle.

Page 26: Presentation sayed

Traffic signs or road signs are signs erected at the side of or above roads to provide information to road users.

Road signs in Malaysia are standardized road signs similar to those used in other nations but with certain distinctions.

Malaysian traffic signs use Malay, the official and national language in Malaysia. However, English is also used for important public places as tourist attractions, airports, railway stations and immigration checkpoint. Some places, both of the language, Malay and English are used in the road sign.

Road Work---Road Sign

Page 27: Presentation sayed

Road signage is including the road marking and also signage board. Most of the road signage put at the T-junction. Hump used to control the speed of vehicles to slow down the speed of vehicles.

The proposed road marking and signage plan is shown in the project plan.

Ministry of Works Malaysia, MOWs tried to provide a better safety of road in Malaysia alongside with the Government efforts to reduce traffic accident and to achieve its targets.

Although studies shown that causes to most of the accident is because of the drivers themselves

MOWs always make it positive effort in order to improve traffic accident by giving further stress on engineering aspect with proactive and reactive action during design, construction and maintenance stage.

DRAINAGE SYSTEMCHPTER FOUR

Page 33: Presentation sayed

Drainage System

Water is the main contributor to the wear and damage of roads. The water can be in the form of ground water, surface water (streams and rivers) or rain and it can damage the road in several ways:

• By washing away the soil (erosion and scouring)• By making the road body less resistant to traffic (i.e. weakening the load bearing

capacity)• By depositing soils (silting) which may obstruct the passage of water, or• By washing away entire sections of the road or its structures.

Typical problems caused by poor drainage include:

---Introduction

• Rutting • Cracking

• Potholes • Erosion

• Washout • Heaving and Flooding

Page 34: Presentation sayed

Drainage System

An efficient drainage system is essential to allow water to flow off and away from the road as quickly as possible. This is achieved by a system consisting of the following components: Road surface drainage which enables the water to flow off the road surface, Side drains which collect and lead the water away from the road, Road embankments in flood prone terrain, lifting the road surface well above

the highest flood levels, Catch-water drains which catch surface water before it reaches the road, Scour checks, preventing erosion in the ditches by slowing down the flow of

the water, Culverts which lead the water from the side drains under the road to the other

(lower) side, Bridges and drifts which allows the road to cross rivers and streams in a

controlled manner throughout the seasons.

---Objectives

Page 35: Presentation sayed

Drainage System

The design of drainage system is based on:

Urban storm water management Manual for Malaysia (MASMA) published by department of irrigation & drainage, Malaysia, 2000.

Polynomial approximation of IDF curves:

Polynomial expressions in the form of equation have been fitted to publish IDF curves for the 35 main cities/towns in Malaysia. From MASMA.

Ln ( r I t)= a + b ln (t) + c ( ln (t))2 + d (Ln (t))3 ……….. (1)

Where:

( r I t)= The average rainfall intensity (mm/hr) for ARI and duration t

r= Average return interval (years)

t= Duration (minutes)

a,b,c,d are Fitting constants dependent on ARI

Sewage System

Sewerage system is essential for any commercial, residential and industrial buildings.

Sewerage system is a network of pipes, pumps, and force mains for the collection of wastewater or sewage, from a community to ensure their hygiene and health.

Modern sewerage systems fall under two categories: domestic and industrial sewers and storm sewers. Sometimes a combined system provides only one network of pipes, mains, and outfall sewers for all types of sewage

---Introduction

Page 45: Presentation sayed

This part is to study and plan for the overall sewage generation and collection based on the present layout plan.

Sewage System---Objectives

Page 46: Presentation sayed

Proposed sewer lines will collect the sewage generated from the new residence buildings, commercial buildings, surau, sport complex and will transfer them using the proposed pipes and manholes to the sewerage treatment plan within the project site.

The proposed reticulation system will consist of HDPE pipe and precast clay manholes.

Sewage System---Proposed Sewage Design

Page 47: Presentation sayed

The design of the sewer pipes and manholes of this project are based on the following standards:

“ M.S 1228: 1991, code of practice of design and installation of sewerage systems” by the standard and industrial research institute Malaysia ( SIRIM).

Page 51: Presentation sayed

The water supply industry is important not only to maintain the health of the community, but for the sustainability of industry, business and agriculture.

Without adequate water supplies our present society would never have evolved, and our lives today would be unrecognizable.

Like the other service providers, electricity, telephone and gas, the water utilities deliver their product to the home, which requires a network of distribution pipes to service each household.

Water Supply---Introduction:

Water Supply

Page 55: Presentation sayed

In order to design the water distribution system we need to know the water demand for our area

Water demand is based on population served, per capita consummation, and service factor, industrial and other special demand.

In estimating water demand, various factors should be taken into account directly or indirectly.

Water Supply---Water Demands:

Page 56: Presentation sayed

Water demand in our area is basically contain 1. 82 units with 5 person each house + Fire hydrant2. Surau 150 person 3. Complex centre 200 person 4. 8 Shopes

Summary of water demand 175380+1200+11000+3000= 190580 L/day

= 190580 L/day X 2.5 (factor)

= 476.45 m3/day

Water required for 3 days

= 476.45 m3/day x 3 = 1429.35 m3/day
