AB Kurre Contracting Dominates Asphalt Recycling With an In-Synch Crushing & Screening Plant
Allen Kurre is not new in the crushing game. He started using mobile crushers early on site-work jobs to turn rock into aggregates. What used to be a project necessity at one point turned into a custom-crushing profit center. AB Kurre Contracting offers complete site work (utility, drainage, grading, site-clearing), excavation, trucking, demolition, and custom crushing services throughout New Jersey.
New asphalt plant with up to 70% RAP
A contract with an asphalt plant that can produce asphalt mixes with up to 70% RAP required him to invest into a high-production asphalt recycling crushing spread. The asphalt producer takes in asphalt millings from local roadwork and chunked asphalt from parking lots with the majority of the material being milled asphalt. Allen realized that a large percentage of asphalt millings doen't need to be crushed but screened and devised a closed-circuit setup with a mobile incline screen and mobile impact crusher.
The asphalt plant can't afford to run out of recycled asphalt
Asphalt recycling is not easy. The material is sticky, shuts radiators, is highly abrasive, and chews up your wearables quickly. All this can result in unplanned downtime and loss of production. If the asphalt recycling process can't keep up with the demand, the asphalt plant is forced to purchase virgin material and triples costs. Therefore, Allen needed a solution to ensure a constant high output with lowest possible operating costs.
The best crushing spread will cost you a lot of money if your crusher and screen don't provide the right performance in the right places.
Production and profit is the aim of the game. Without maximizing output and minimizing your costs your are trapped with the going market rates and struggle to increase your return on investment. There is a common misperception that you need a big crusher for a big crushing job. A mix of asphalt millings and plant waste doesn not require a lot of crushing and the little crushing that is left can be easily handled by a RM 70GO! Compact Crusher.
Maximized crusher & screener utilization
Both plants are operated at ideal capacity and you don't waste valuable money on an expensive large impact crushing plant that is underutilized. Too big of a crusher would burn excessive fuel and you increase your maintenance requirements and battle with keepting the crusher running.

What is asphalt recycling process?
Millings and asphalt chunks are collected from road-work and parking lot renewals and stockpiled in separate piles. A 20-ton excavator feeds chunked asphalt into the an impact crusher for an initial reduction in size. The crushed asphalt is fed into a 3-deck incline screen that classifies the material into 3 recycled aggregate products,which are reused by the asphalt plant in new basecoast and topcoat hotmixes. Depending on the state and type of asphalt plant new hotmixes can contain up to 60-70% of recycled asphalt. However, the majority of asphalt plants in North America operate on a much lower recycled asphalt level.
The indline screen also produces a 4th oversize product that is recirculated back into the hopper of the crusher to be recrushed in a second run. In addition, a wheel loader feeds asphalt millings directly into the feed hopper of the screening plant because the majority of the product contains fines that don't need to be crushed initially. By feeding millings into the screening plant you reduce wear on your crusher consumables and increase production.
How does asphalt recycling reduce costs?
Asphalt is the most recycled material in North America by volume. Disposal costs in New Jersey hike due to the ever-increasing volume of removed asphalt pavement. This calls for asphalt plants that accept more recycled asphalt. Processing old asphalt into new aggregates saves costs 2 ways. First, crushing asphalt produces new aggregates to reduce the cost of purchasing virgin material without sacrificing quality. Second, the oil (also called bitumen or binder) on the stone can be rejuvenated to reduce the amount of new bitumen needed to produce new blacktop.
According to the New Jersey DOT the cost of asphalt cement has been on the rise from $360 per ton to $530 per ton in January 2022. The rising cost of bitumen correlates with the rising cost of crude oil, which is the base product. Without increasing the percentage of recycled asphalt in the mix you lose money to high production costs and are exposed to constantly changing oil prices.
"We keep you crushing with a strong support team, numerous stores throughout New Jersey, Maryland, and Delaware, and years of experience maintaining mobile crushing & screening equipment."
