From the relation between dry density and water content of RAs as well as NAs, the optimum moisture and maximum dry density were also determined. And during compac- tion, the mortar in concrete and masonry was probable broken, resulted in increase of the density.

crushed aggregate cbr test

Relations between NFA, RAs sand and cement content – The compressive strength and splitting tensile strength of RAs sand increased as cement content increased, this is similar to the rules occurred with natural sand. The penetration resistance of the plunger into a 22tch sample of crushed stone for the corresponding penetration is called std load.

In other cases 1. During vibration of the sec- ond layer, the material is fulfilled. Only the people who dare to fail, will achieve big success. This document is only used for personal research purposes and not to used for business or other profitable activities.

This supports to the ability of using RAs for wet road layers with a fast draining capability for the surface layer. National University of Civil Engineering. Procedure of construction and acceptance of the cement treated sand layer for pave- ments. The properties of cement meets the requirement s of TCVN CBR is frequently used as test value for civil crushed rock as a percentage value.


The results focused on effects of cement content on some subgrade proper- ties such as: RMA has composition of brick and mortar debris which is lighter than NAs, this may decrease the maximum dry density of RMA to the smallest.

There are two types of recycled aggregates RAs from two different sources, RA from masonry debris called recycled masonry aggregate RMAand RA from concrete or concrete reinforcement structures called recycled concrete aggregate RCA.

Maximum dry density and optimum moisture content are determined using the standards for transpor- tation 22TCN Please support the website and help the community by sending your documents to us. The results indicated that CDW could replace natural aggregate in road base layers in Vietnam. Join the activities on me. Remember me on this computer. Particle size distribution of natural aggregate and RAs – From Table 4, we found that: Hanoi, 26 – 27 March Utilisation of construction demolition waste as stabilised materials for road base applications Tong T.

Vibrating compacted density is determined in the following procedure: If your documents are loaded by many people. Strive not to be a success, but rather to be of value. The basic properties of natural aggregate and RAs No.

When RAs sand used for the upper layer of the high performance pavement and surface layers with bitumious laminatation, the cement content needs to be added about 6. Many old buildings have been demolished and replaced by new buildings.


Life is a tragedy when seen in close-up, but a comedy in long-shot. In ad- dition, research on utilisation of CDW for road foundation has not been interested in Vietnam. Relations 22ctn compacted density of 22tcm and vibration time – In general, increasing the vibration time increased, the compacted density of RAs mixture, especially 222tcn vibration from 0s to60s.

The CBR was found to depend on the properties of the constituent materials and the compactive effort used to prepare the. Construction soil- Testing method for determine partical size distribution in labratory. Click here to sign up. Thanh2 and Phung V. Such documents may concern. Wear a smile and have friends; wear a scowl and have wrinkles.

The compressive strength and splitting tensile strength are determined using the standard for transpor- tation 22TCN Design standard for high way. Cement PCB30 Hoang Thach, available on the Vietnamese market, was used in this research to inves- tigate the possibility of RAs used for road foundation layers reinforced with cement. You can’t start next chapter of your life if you keep re-reading the last one.

There are no construction procedures and standards for testing as well as specifications of recycled CDW materials when they used for foundation layers and pavement road. Natural coarse aggregate and RAs mixture using compac- tion method I-D mould with The results obtained are shown in Figure 8. Utilisation of construction demolition waste as stabilised materials for road base applications.
