Avoid Paving Scams: There are leftover materials from another job. Professional asphalt contractors know, with great accuracy, how much paving material is needed to complete each project. Rarely will they have large quantities of leftover material.
 You are pushed to make a quick decision. Trustworthy contractors will give a written estimate that will be valid for days or weeks. It should specify in detail the work to be performed and the total price. They also don’t mind you checking them out before signing a contract.
 Cash-only sales. Most reputable contractors will take checks or credit cards.
 The company is from out-of-state. Look at the truck the representative travels in. If it is unmarked or has an out-of-state license plate, be cautious. Even if the representative claims to have a local phone number, scammers can easily buy disposable cell phones to give a local number in the area they are soliciting. Also, don’t be afraid to ask to see their driver’s license.
 Ask to see registration. Verify it with the Contractors Registration Board. https://snakeriverbbb.wordpress.com/2013/08/26/bbb-warns-of-eastern-idaho-residents-of-possible-paving-problems/ http://www.localnews8.com/news/scam-alerts/be-alert-for-asphalt-paving-scams/590575963
