Asphalt Industry
From 2012 to 2015 ALDOT let over 3 Billion Dollars in Construction work. Of that amount, approximately 53% of funds went towards asphalt related items. This was a major investment for the taxpayers of Alabama.
A good roadway network is critical to the economy.
Each and everyone of us and our families drive on asphalt roadways daily.

Feb. 1, 2016 letter to ARBA and AAPA:
Attached is Special Provision No revising Item (h)2 of the specifications to allow a Weighmaster to electronically sign weight tickets when a scale location has remote ticketing capability. Please note that this allowance also requires additional information to be included on the weight ticket; specifically, the maximum legal load for the haul route and the name of the pay item being delivered.
This Special Provision will be included in proposals starting with the February 2016 letting, and may be considered applicable to any current projects on which the Contractor has the capability to meet the new specification requirements.

12. Electronic Weighmaster Signatures
Feb. 3, 2016 letter to ARBA and AAPA:
An aggregate supplier contacted this office asking for clarification of the intent of our February 1, 2016 letter stating that the Department would begin allowing electronic signatures on weight tickets at scale locations with remote ticketing capability.
The supplier asked if it would also be allowable to utilize electronic signatures at scale location that do not have remote ticketing capability. At such locations, the Weighmaster would sign the ticket electronically, but still physically deliver the ticket to the driver. The answer to the supplier’s question is yes, the Department’s will allow electronically signed tickets delivered in this manner.
