approach to investigation and assessment of construction materials is specifically tailored to that environment. There is also a greater need to view the application of specifications and construction practices in terms of a whole road unit, including earthworks and drainage, rather than in terms of individual pavement layers.

ROAD DESIGN 3.1 Horizontal and Vertical Alignment . Center line alignment influences haul cost, construction cost, and environmental cost (e.g., erosion, sedimentation). During the reconnaissance phase and pre-construction survey the preliminary center line has been established on the ground.

Before any type of road construction method is considered, soil testing must be carried out, which is known as cbr testing or The California bearing raito. This test is performed by measuring the pressure required to penetrate the soil or aggregate with a standard area plunger. The harder the surface the higher the CBR.

Physical requirements of course aggregates required for construction of WBM road in terms of test values for different pavement layers is given below. b ) Screenings : The material which is used up to fill up the excess voids present in the compacted layer …

Asphalt Mixing Plant. Asphalt Mixing Plant is another important road construction equipment. If the project is a large one, then the asphalt mixing plant is set on the road construction site. In this process, the concrete asphalt including other materials including macadam and coated roadstone are mixed together in correct proportion.

Pavement Design in Road Construction. BY Kiran Biradar. Introduction. Pavement design is the major component in the road construction. Nearly one-third or one-half of the total cost of construction, so careful consideration should be taken in design of pavement. ... Test should be done per km depend on soil type. If CBR less than 2% for 100 mm ...

Issue: Road is lower than surrounding grade. Surface erosion is occurring and there is no way to get water off road surface. Fix: This is the most challenging section of Horse Point Road to address. To significantly improve this section would require a complete rebuild to raise road 1' above existing grade.

in bending. It is useful in knowing the quality of concrete work done in road construction. Because of low initial cost, flexible roads are preferred, to concrete road pavement, but b roads getsituminous deteriorated during rainy season and maintenance becomes costly, therefore . Government agencies have decided to go for concrete roads.

In general, the construction of road shall be started after completion of works related to sewerage, drainage, water supply etc. for the stretches of the road. As
