We are experts of all kinds of subgrade preparation, and are industry leaders in asphalt and concrete construction. Neighborhood Rehabilitation As part of our growing commitment to responsible and sustainable construction techniques we have incorporated the technique of Full Depth Reclamation as part of our road rehabilitation portfolio.

46 Figure 1. Relation between permanent strain and elastic strain for buckshot clay. stresses at the surface of the subgrade should be the same for any wheel loads.

The intent of the Mirafi® RS380i was to provide subgrade stabilization, separation between soft subgrade fines and base material, as well as decrease the total thickness of pavement sections. Mirafi® MiraSpec software was used to calculate the reinforced pavement sections us .

Index 199 to Section 985 changes (3) The Engineer may test components in a blend of rubble processed from different geologic formations, members, groups, units, layers or seams.

gate; (ii) improved vertical stress distribution on subgrade; and (iii) reduced shear strain along the top of the subgrade. • Tensile Membrane Support, which develops if high strains are mobilized. • Increased Bearing Capacity, which may develop by constraints imposed in the development of failure surfaces through the subgrade.

existing pavement and replacement with either concrete or asphalt. The design of new concrete and asphalt is given in Sections 300 and 400 respectively. Subgrade Determination To design all major rehabilitations, including complete replacement, it is necessary to know the strength of the subgrade under the existing pavement.

The HMA Pavement Mix Type Selection Guide provides designers with methods for selecting appropriate mix types while considering factors such as traffic, environment, subsurface pavement structure, existing pavement condition and preparation, and economics. The pavement mix types targeted are OGFC, SMA, and fineand coarsegraded dense mixes.

Calculating hardcore quantities allows you to purchase the correct Pavement Base, Subbase, and Subgrade Layers for Cost signed and constructed to provide the most economical life cycle cost . subbase materials d) Pavement thickness, from 6 in. to 11 in. e) Annual average daily traffic (AADT) from 110 to 8900.

reasons why concrete is the best pavement choice: Rutting is the permanent deformation of pavement layers which can accumulate over time Highway rutting is common due to high channelization and higher repetition traffic.

BETTIS COMPANIES. The Bettis name is synonymous with quality and integrity in Eastern Kansas and throughout the Midwest. Working with Bettis means working with .

porous asphalt pavements expected to carry truck loads, structural design should follow standard design procedures. Recommended layer coefficients for porous asphalt pavements are shown in Table 1 (Hansen, 2008). Recommended minimum thicknesses of the compacted porous asphalt layer for different truck loadings are shown in Figure 3.

processed to create an alternative aggregate material. Sources of concrete and asphalt rubble included asphalt street rehabilitation projects, concrete sidewalk replacement programs, asphalt and concrete roadways, excavations from building demolition, as well as material from private contractors such as parking lot reconstruction, etc.

Porous asphalt is an environmentally friendly tool for stormwater management. POROUS ASPHALT PAVEMENTS In the natural environment, rainfall sinks into soil, filters through it, and

Porous Asphalt Pavement Performance in Cold Regions What Was the Need? Porous asphalt pavements, designed with higher air voids, allow water to drain directly through the opengraded

While the terminology (, thickasphalt pavements, longlasting asphalt pavements, longlife asphalt pavements, deepstrength asphalt pavements, extended life HMA pavements, and fulldepth asphalt pavements) may differ from place to place, the basic concept is .

Whether your project was large in scale or very small, we will take your concrete and asphalt rubble and process it through a crusher. The resulting product is recycled and can be used for other products.
