ASPHALT ANSWERS parking lots , streets and even walking trails can see enough savings on the first couple jobs to pay for the investment . Remember , grade control works on averages , so the longer the pull , the better the average . Some things to remember when considering grade control are not only the return on investment , but crew training . If your team does not understand how to use grade control , they will not want to use it . So whatever you decide to buy , make sure it comes with a good training program . Another would be sub base . Do you control the sub base or is it handed to you by the GC ? If there are high spots in the base then you will have thin asphalt in those places . It is best to have the base put in with grade control if you are going to use it for the asphalt . There are also several choices of grade control ; single grade or joint matcher , dual grade and dual grade and slope . Each have their own benefits . Single grade or joint matcher is just that it controls one side of the screed , matching a joint or curb reveal . This leaves the opposite side to be controlled manually . This is easier to use and works well on smaller jobs as well as some bigger jobs . The dual grade is just what it says , it matches both sides to a controlled reference point be it a curb , string line or the last pass . This is more money and takes a little more set up and training . The last is dual grade and slope . It is the most expensive and takes the most training and setup . So , if grade control is something you have considered , first look at what work you do . Get buy in from your crew . Also , talk to the dealer that sells pavers ; they most likely have a relationship with a local grade control supplier and can tell you who has the best product and service in your area .
