Cement-Treated Base CTB is a non-conventional method used in road bases materials to improve its engineering properties due to the hardening of cement when moisture is present and extends the period of curing times. This study investigates the effects of cement additive on properties of base layer using laboratory mechanistic evaluation of stabilized soil mixtures. The results revealed that by adding Portland cement, the mechanical properties of the mixture have improved where the UCS is found to be an important quality indicator. In addition, the variables that influenced these tests, which are cement content, curing time, moisture content, and dry density, play important role to determine the performance of CTB. This paper presents the finding of a correlation conducted to analyse the influences of these variables using regression and ANOVA to establish significant models with the aim of predicting the strength base on mixture parameters. Introduction For road bases, there is a variety of soils or granular materials available for construction, but they may exhibit insufficient properties e. However, some addition of a stabilizing agent such as cement, bitumen, lime or some non-traditional agents can improve the properties of soil. Among these different stabilized materials, cement-bound materials develop a quite high stiffness and strength, and exhibit good performance for pavement serviceability and high durability. Stabilized bases can provide cost-effective solutions to many common designs and construction situations. Cement-Treated Base CTB is a traditional method applied in road bases materials to improve its engineering properties due to the hardening of cement when moisture is present and extends the period of curing times. Bound base materials provide additional strength and support without increasing the total thickness of the pavement layers. Depending on project needs, CTB increases the construction speed, enhances the structural capacity of the pavement, or in some cases reduce the overall time project. In addition, a stiffer base reduces deflections due to heavy traffic loads, thereby extending pavement life. Base thickness of CTB is reduced because of high bearing strength compared to unbound granular base thicknesses [].

The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.

In this system, the pound lbf represents a unit of force weight , while the unit for mass is slugs.

This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Indeed, there is need for the Nigerian government to embark on commercial production of the Chikoko pozzolana due to the abundance of the Chikoko mud in Niger Delta of the country as well as the need to supplement the limited supply of fly ash from Oji Rivers Station, which at the moment, is the only source of fly ash in Nigeria.

This development may lead to see to the extensive use of Portland — pozzolana cements in future. In fact, the U.

Since fly ash is produced from only one power station in Nigeria, with a production rate that may not meet demands, it is recommended that the Nigerian Government should embark on commercial production of Chikoko pozzolana, since the chikoko mud is abundant in the Niger Delta of Nigeria. Thereafter, government can specify the use of the pozzolana in appropriate construction especially, those funded directly by government.

In addition, they are representative of the significant digits that generally should be retained. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering data. The values stated in each system shall be used independently of the other.
