Pavement performance can be largely attributed to the care given in designing and preparing its foundation, which is comprised of the subgrade and base layers.May 05, 2019 May 05, 2019 A solid subbase is a key to a successful building project. A slab on ground and pavements normally are designed to be supported by a solid subbase, which needs to be uniform by nature to support the structure above it. A subbase will go on top of the subgrade, which typically is native soil or improved soil that has been compacted.Aug 10, 2020 Aug 10, 2020 The sub-grade surface is the top of the embankment and the surface upon which the sub-base is placed.

    pavements are generally attributed to poor sub-grade conditions. These are the main reasons why Improvement in sub-grade has always been an area of concern to highway and geotechnical engineers. In case of a highway, a weak sub-grade results in greater thickness of pavement layer which increases the cost of pavement construction.

SOIL In the structure of highway, embankment and subgrade are to be constructed with soil.withdrawn from a soil. It has been found useful in evaluation of sub-grade sub-base materials. Teme and Anowaii 1987, Madedor 1983 and FMWH 1974 have specified standards limits for sub-gradesub-base materials for highway pavements. As shown in Table 3, the liquid limits of soil samples from the unstable locations range from 34.connection to Highway 401 West Durham Link, the subgrade soil has been investigated with nearly 700 test pits and boreholes, evenly spaced along the route, over nearly 30km. The subgrade soil resilient modulus was measured using a light weight deflectometer LWD in some test pits.
