| Abstract: | Engineering nature of expansive soil is extremely complicated.It is larger influenced by environmental factor,expends after imbibing the water,contracts and cracks after loss of water,which lead to destruction of subgrade.This problem all the time is a large technical difficult one that affects highway building in our country.Modifying the expansive soil with the lime is capable of eleminating the contractibility of the soil,strengthening the strength and stability.The paper makes an approach to constructio... |
