Typical Road Structure Cross Section

As base course lies close under the pavement surface it is subjected to severe loading The material in a base course must be of extremely high quality and its construction must be done carefully The material in a base course must be of extremely high quality and its construction must be done carefully...

3 Aggregate Properties

Strength is a measure of the ability of an aggregate particle to stand up to pulling or crushing forc Elasticity measures the "stretch" in a particle High strength and elasticity are desirable in aggregate base and surface cours These qualities minimize the rate of disi ntegration and maximize the stability of the compacted material The ....

Aggregates

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar Those particles that are predominantly retained on the 475 mm (No 4) sieve, are called coarse aggregat Those particles passing the 95 mm (3/8 inch)...

The Complete 7

This process involves undercutting the sub base, but instead of removing all of the soft clay and soil, it is instead mixed with added aggregate to improve the strength of the compromised areas Step 5: Binder and Surface Course Once the sub base is laid and any soft areas are identified and repaired, it is time to add the binder...

Coarse Aggregate: Definition & Density

Coarse aggregates are components found in many areas of the construction industry They have structural uses such as a base layer or drainage layer below pavements and in mixtures like asphalt and ....

Bituminous Surface Treatments

Bituminous surface treatments (BST) refer to a range of techniques that can be used to create a stand-alone drivable surface on a low volume road, or rehabilitate an existing pavement Usually, the term is used to describe a seal coat or chip seal, which is constructed by spraying a layer of emulsified asphalt, and placing a layer of aggregate on top BSTs can be applied directly to a base ....

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...

Base course

The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting fieldIt is located under the surface layer consisting of the wearing course and sometimes an extra binder course If there is a sub-base course, the base course is constructed directly above this layer...
