Larry Spring started working in the construction industry in 1968 as an equipment mechanic for a construction and paving contractor. He worked until 1986 as a field service technician on all construction equipment used in heavy highway and building projects. In 1986 he went to work for a Blaw-Knox™ paver distributor as shop foreman and field service technician. In 1996 he worked in the Northeast with the Blaw-Knox™ sales team. He has also worked with the National Accounts as a Product Specialist for road building customers. In 2010 he joined LB Performance Paving as Training and Technical Manager. Larry has been in the paving industry for over forty years and has a wealth of knowledge to share. Here are some of his tips.
- Properly maintaining end gates are essential for ease of adjustment and quality material at screed edge.
- End gates that are straight and kept free of cold asphalt debris yield the highest quality joints and unsupported edges.
- To maintain quality mat texture screed plate wear needs to monitored periodically.
- It is recommended daily inspections are conducted to check crown and plate flatness.
- To detect uneven wear of the screed plate during operation, observe defects in mat quality.
- If defects are encountered, inspect plate.
- If plate is defective, replace immediately with Genuine Blaw-Knox™ Screed Plates.
- Detailed inspection and maintenance procedures can be found in your machine’s screed operation manual.
- With cooling temperatures upon us, it is even more vital to properly cleanse equipment at the end of each paving day to avoid excessive wear on components. This will diminish high-system loads and stresses during next-day start-up. By keeping wear surfaces such as conveyor chains, drive sprockets, floor plates, bearings, and hopper hinges clean and properly lubricated, the user will experience extended component life. This will help avoid costly repair and promote equipment up-time.
- Common use of modern sonic joint matchers provide quality and dense joints. Many contractors will operate depth controls manually, however, employing a joint matcher control system is encouraged to yield consistent joint quality critical to overall mat value.
- The best paving performance result from a crew that works together and communicates. In my experience discussions prior to start-up to review objectives and responsibilities for individuals as well as the team yield the best results. This helps keep the team on the same page and makes the intentions, for the day clear. Refer to paving manual for recommendations.
