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.

Northeastern Thailand occupies about one-third of the total area of the kingdom, and this region is physiographically called the Khorat Plateau.

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.

Stabilized base or subbase materials may be used to provide support for either flexible or rigid pavements, but are more frequently used with flexible pavements. Stabilized base or subbase materials are either mixed in place at the job site, or are mechanically combined in a supplement to Caltrans Design and Construction Manuals.
This guide does not supercede Caltrans or Federal standards, specifications, or regulations. ACKOWLEDGEMENTS The assistance and interest of Mr. Rich Haro and Mr. Donatas Greb of HSI Engineering with regard to strength testing of cement stabilized materials is acknowledged.

The existing unpaved road section was pulverized to a depth of 12 in and subsequently blended with 5% cement by weight using road reclaiming Soil compaction is defined as the method of mechanically increasing the density of soil.
In construction, this is a significant part of the building process. If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs or structure failure. Almost all types of building sites and construction projects The effects of CS on the CBR of (i) soil–CS and cement-stabilised soil–CS mixes and (ii) fly ash–CS and pond ash–CS mixes, using the data taken from the studies undertaken in India sinceare plotted in Figure (a) and (b), the specimens used were reported to be in the soaked condition, except for Patel et al.

This study examines the small-strain dynamic properties of cement-stabilized silty clay (CSC) and cement-fly ash-stabilized silty clay (CFSC). A series of resonant column tests were performed to investigate the effect of confining pressure, binder content and curing age on the small-strain dynamic shear modulus (G) and damping ratio (D) of CSC and :// In this paper, combined with the construction of shangqiu to kaifeng freeway, the component design method of cement - stabilized silty soil and the strength, modulus and anti - cracking performance of the mixture are researched systemically in lab and on Design and construction of the embankments involved: staged preload construction with surcharging to reduce post construction settlements, installation of wick drains and use of lightweight fill materials to reduce the construction time period, and geogrid-reinforced concrete block walls to This demonstrated structural performance improvement has the potential benefit of facilitating the construction of roads of a quality comparable to paved roads at 20% of the cost with fewer traffic interruptions.
