Roads - A Software for Pavement Design and Rate Analysis of Roads Website: Contains 76 Numbers of Design Programs Including Flexible, Rigid Pavements, Geometry & Traffic, Highway Economics, 54 Nos.
Jointed Plain Concrete Pavement (JPCP) Joints accommodate shrinkage during drying.Course Description: Modes of Transportation, their importance and limitations, the importance of highway transportation Introduction to Road Development Plans Various Highway Developmental Projects like Golden Quadrilateral and East- West & North South Corridors under NHDP, PMGSY etc.
Types of Flexible Pavement Dense-graded Open-graded Gap-graded
Surface course (waterproof, anti-skid).
Cementing material can be portland cement or asphaltic cement, or other material. roads use rigid pavementįlexible Pavement Base: higher strength material than subbase, often a cementing material is used.
Called “rigid” since PCC’s high modulus of elasticity does not allow them to flex appreciably.
Portland cement concrete (PCC) pavements.
Called "flexible" since the total pavement structure bends (or flexes) to accommodate traffic loads.
What pavement thickness is required to sustain X vehicle loads of Y weight? Pavements degrade over time due to Exposure to traffic Time Exposure to elements Different for different materials and different construction methods Serviceability Concept

Develop methods to relate physical attributes to driver ratings.
Volume of vehicles and prediction of vehicle volume is fundamental to pavement design.
Pavements have a design life, and fail after cumulative vehicle exposure.
Trucks and busses present a much more significant load on the pavement.
Truck can weigh up to 80,000 lb with tire pressure of 100 lb/in2.
Typical vehicle weighs about 3500 lb, tire pressures around 35 lb/in2.
Want to distribute the load to avoid permanent deformation.

Pavement (material), the durable surfacing of roads and walkways ("road surface" in British English).
to cover or lay (a road, walk, etc.) with concrete, stones, bricks, tiles, wood, or the like, so as to make a firm, level surface.
