The foundation of the road is known as the sub grade and is usually done with hard compacted murrum [ 600 to 750 mm thick ]. There are methods to decide /measure and control the moisture content which achieves optimum consolidation of the murrum.

Two models were studied, one of which is reinforced by single layer of geotextile at subbase- subgrade interface and the other using single layer of geogrid at the same depth to improve the subgrade, grouting technique is used through the injection of the subgrade with a mixture of cement, bentonite, and water.

The grout particle size and void size must be matched properly to allow the cement grout to permeate. Depending on the conditions, Portland cement or microfine cement grout is injected under pressure at strategic locations through single port or multiple port pipes.

The Federal Highway Administration program to promote this technology appears to have had a significant impact. Over 17 states reported to have used a video camera. Many agencies own their own video camera, with a cost for the system ranging from $13,000 - $40,000.

This paper presents an innovative use of soil-cement mixing method using jet grouting technique to improve the bearing capacity of subbase foundation for road construction in Thailand.

The advantage of using jet grouting as a subbase foundations is a simple for road construction works on soft clay. Based on the analysis of the jet grouted piles, the reduction of the total settlement was found to increase with increasing column area ratio, with increasing column length ratio, and with increasing shear strength of the jet ...

Concrete road slabs have a tendency to sink or rock during the course of their serviceable lives, due to instability of the underlying sub-base material, usually brought about by water flow or pumping action beneath the slabs.

Geosynthetics are extensively used as a civil engineering solution to reinforce unbound aggregate layers in highways, unpaved and paved roads, runways, railways, …

Subbase transition to an existing subgrade or subbase will be a minimum of 12 inches (300 mm) of depth per 50 feet (16 m) of horizontal length. Existing subbase left in place will be transitioned with new sand subbase material to avoid differential frost heave.

The best way to know if the subbase is properly compacted and ready for the slab is by proof-rolling, which is running a heavily loaded truck (such as a fully loaded concrete truck) across the subbase immediately before placing the concrete to see if any areas sink more than others.

The No. 2 subbase thickness is typically 6 to 18 in. (150 – 450 mm), depending on the amount of water storage required, as well the amount of traffic and soil type.

Grouting & Road Void Grouting Techniques Concrete road slabs have a tendency to sink or rock during the course of their serviceable lives, due to instability of the underlying sub-base material, usually brought about by water flow or pumping action beneath the slabs.

Foam concrete is a type of lightweight concrete which is lighter than conventional concrete. It is non-load bearing structural element which has lower strength than conventional concrete. Foam concrete is widely used in construction field and quite popular for some application because of its light weight such as reduction of dead load, non-structural partitions and thermal insulating materials.

Subbase stabilisation is the process of stabilising existing subbase layers or imported subbase materials to substantially improve performance. As well as enabling re-use of existing materials, the performance improvements delivered by subbase stabilisation also reduce the volume of premium aggregates needed.
