Fine Grading (Figure 7-2) the subgrade for aggregate or asphalt base courses is usually conducted with a motorgrader and checked with a stringline, but may be conducted with an automatic grading machine controlled from a stringline. The automatic grading machine is required to be used for preparing the subgrade for concrete base and pavement. When
E. Surface Course - The upper portion of the pavement structure consisting of a mixture of mineral aggregates and bituminous material or Portland cement concrete. This includes all wearing courses (e.g. asphaltic concrete friction course). F. Pavement Structure - The combination of subbase course, base course, and surface course placed on the
A frayed joint where the concrete has been worn away along the entire joint is rated as low severity. X2.21.3 How to Count —If spall is along the edge of one slab, it is counted as one slab with joint spalling. If spalling is on more than one edge of the same slab, the edge having the highest severity is counted and recorded as one slab.

Aggregate Base Course construction will be done half of the road way at a time and other side permits to go vehicles with out any disturbance. Before starting the ABC construction both side shoulder preparation will be done for some extend to avoid the wasting of ABC and to shift away of aggregates at the edge compacting.
CHARACTERISTICS OF GRADED BASE COURSE AGGREGATES DETERMINED BY TRIAXIAL TESTS. Several series of triaxial compression tests are made to determine the effect of miximum size of aggragate, of fines passing No. 200 sieve, of plasticity, of shape of particle, of type of aggregate, and of blending aggregates of different types, on the strength and deformation of dense graded base course …
Below is very brief road construction work method statement that outlines the complete process from laying the sub base to the laying of asphalt to achieve final product or outcome.

This should be compared to an unbound aggregate base material. The comparison is to see if any distresses prematurely appear, if the stiffness strength changes negatively,f permanent deformations occur. or i 17.

The most common method of stabilization consists of mixing hot bitumen with an existing mixture of ground-up HMA surface and aggregate base. The layer of stabilized material is then used as a base course for a new HMA surface. Stabilization increases the bearing
coarse aggregate present. The results indicate that for mixtures containing coarse aggregate, a number of laboratory test methods, including AASHO Method T-99, Alternates C and D, fail to produce densities nearly as high as the den sities readily attainable in the field. Therefore a collateral study, to

2.1.2. RAI. The RAI used in this study are selected from the recycled material of the base course of Linxia section of the provincial pavement in Linfen City, Shanxi Province. 56.2% of the coarse aggregate and the measured crushing value of 10–15 mm reach 25.8%, and the sand equivalent of the fine aggregate of the RAI reaches 75%, with a great degree of cleanliness, which is conducive to the ...
crusher-run aggregate and compacted in laboratory as well as field experimental sections. The following were observed: The aggregate fractions must virtually be "packaged" to interlock such as to form an aggregate matrix that approaches the condition of the intact parent rock – so called a "solid density".
Aggregate: A component that resists compressive stress, such as sand, gravel, or crushed stone. Base System: A designed system of materials that provide porosity and stability such as soil, crushed aggregate, geotextiles, and drain lines. Drainage System: A method of removing surface and subsurface moisture / water.
