ROADBOND EN1 – Soil Stabilizer
Installation was quick and easy. No transportation trucks and no remix. Finished in one day. Soil worked well and is easily cut and placed on grade.
Shed water well and is hard and tight.
In October of 2005 the city of Dallas used ROADBOND EN 1 in lieu of lime stabilization on several alley reconstruction projects. The Satsuma Drive alley was the initial alley project. The subgrade soil was dark brown clay with a P.I. over 40. The existing alley was excavated to lower the grade which allowed six-inches of stabilized subgrade and 6-inches of reinforced concrete pavement. The lines and grades were established and on Wednesday October 26th the clay soil was stabilized with ROADBOND EN 1 to a depth of 6-inches. It was placed, mixed, compacted and finished all on the same day.
On Monday October 31st, the site received over 2-inches of rain and as the photo shows, completely submerged the alley. That afternoon, the contractor pumped the standing water off the site.
The next morning workers began to set the forms for the pavement. Although the surface was wet, the section was not soft, but remained stable and could support construction traffic. On Wednesday the lab took densities. Before the rain densities ranged from 96% to 101% and after the rain densities ranged from 97% to 103%. Although the section stood water, penetration into the subgrade was minimized because ROADBOND EN 1 significantly reduced the permeability of the clay soil.
On Thursday, the forms and rebar were in-place and Friday morning the concrete was poured. From Monday afternoon standing water to Friday afternoon paved with concrete. ROADBOND EN 1 routinely surpasses the capabilities of conventional stabilizers.
