4 More Technological Advances in Asphalt Paving

We recently wrote a blog post on technological advancements in asphalt paving, but there just wasn’t room for all of the updates being made in the asphalt industry. So, to keep consumers informed, we are giving you another blog outlining the old and new in asphalt paving. Our experts on sealcoating in Sheldon, CA, offer the following information on old and new approaches to asphalt paving services.

Sub-base evaluations

Before installing asphalt, the sub-base needs to be tested to ensure it will solidly support the asphalt structure with durability and integrity.

The old way

In any paving installation, a sub-base is laid, and paving can begin after it is impacted. However, there is no way to ensure that the sub-base has the structural integrity to support the weight of asphalt paving and heavy traffic patterns without testing. Even the most minor pockets of unstable sub-base can cause significant issues in an asphalt structure and lead to expensive repairs down the road.

The new way

The availability of nuclear density testing and a proof roll makes testing to determine the durability of the sub-base and overall structural integrity accessible. A proof roll is completed by using a huge, fully loaded four-axle truck over the sub-base to find any areas where it flexes more than an inch. In addition, nuclear density testing is used to evaluate the density of the sub-base material. The ideal compaction rate is 99%. When combined, these testing methods allow asphalt contractors to be confident that the base of their asphalt structure is solid and robust.

Automatic slope and grade controls

When starting new asphalt installations, laser-guided transits program grids are used for automatic grading of the sub-base in asphalt installations to ensure adequate drainage.

The old way

Compactors and graders have not always had settings for automatic grading that would test the slope and grade to ensure proper drainage abilities.

The new way

Newer paving machinery, like motor grades, are equipped with automated slope and grade controls allowing professional pavers the convenience of utilizing established grading grids. This automation removes the risk of human error in the grading process by employing an automated grader blade that follows precise percentages to guarantee proper drainage and grading. This new technology lets paving professionals ensure that water run-off and improper drainage do not compromise the structural integrity of asphalt pavements.

Tear off and removal

The comprehensive removal of existing concrete or asphalt is essential to begin asphalt installation projects anew.

The old way

In the past, cutting the old pavement surfaces for removal was done with a 14-inch diamond blade walk-behind road saw.

The new way

The Road Hog, a new hydraulic technology, allows paving contractors to cut through old pavement with 2-inch-wide trenches, lowering removal times and consumer costs in the process.

Site prep

Contractors must decipher and access depths and heights to prepare appropriate asphalt installation drainage plans.

The old way

In the past, paving professionals were forced to use a plumb-bob and look through a transit, or site glass, to find the linker rod-guided target.

The new way

Laser-guided transits allow paving professionals to decipher height from a long-distance using laser technology. As a result, contractors can quickly determine grades and elevations to create an optimal drainage plan.

These are just a few of the technological advancements made in the paving industry in recent years. Contact us today about asphalt installation and sealcoating in Sheldon, CA. We want to be your blacktop professionals!
