Abstract
Sand is the most available construction material in Bangladesh. Sand- cement stabilization is more cost effective and environment friendly for the construction of sub-base pavement layer in perspective of Bangladesh. The researchers conducted an investigation for the use of cement stabilized fine to medium sand in the construction of roads. Sands from various location such as—Mymensingh, Fajilpur Munshigonj and Sunamgonj are procured for this research work. Although Sunamgonj and Fajilpur sand are slightly expansive, those sand can be easily used as a substitute of unbounded material. According to the laboratory tests, all of the four types of sand have satisfied the criteria of sub-base layer strength on 14 days. The sand-cement material with 8 to 10% cement proved to be adequate for sub-base layers of heavily trafficked roads. It is observed that, sand sample with 8% cement mixes obtained from Fajilpur and Sunamgonj fulfill the specification requirements of sub-base layer for low traffic roads. On the basis of quantitative evaluation, appropriate sand-cement stabilization systems for roads need to be exercised and suggested.
