Pavement line marking refers to painting lines and symbols on surfaces that have been paved with asphalt. Many asphalt paving companies offer these services both for customers who have them install asphalt and others. However, there are also separate companies that do not install asphalt but that focus on painting line markings on asphalt when their customers need it. Pavement line marking is popular and has to be done regularly for these reasons, but luckily, finding a service to help you with pavement line marking shouldn't be overly hard.
