AMIGUARD™ Rapid Penetrating Emulsion Rejuvenator: An Early-Life Preservation Solution

Asphalt pavements begin aging immediately after construction. Both physical and chemical changes to the pavement occur as a result of oxidation, UV exposure, presence of moisture, freeze and thaw cycles, and traffic wear. Early life aging can quickly lead to severe functional distresses such as raveling and cracking and set the stage for more costly downstream structural repairs. Early-life preservation treatments are critical to extending maintenance timelines and lowering life cycle costs of asphalt pavements.

Preparing for Indiana’s Specification Change

The Indiana Department of Transportation (INDOT) announced a significant change in asphalt binder specifications in 2024, transitioning from PG 64-22 to PG 58-28. This change, effective for contracts let on or after September 1, 2024, affects all base grade liquid asphalt binder in Indiana as well as the testing requirements (from AASHTO M320 to AASHTO M332, incorporating AASHTO R92 requirements). In addition, the terminology of which liquid asphalt binders are referred to will be updated to align with these changes.

Paving the Future: Montana Highway 200

Road managers know that the longitudinal joint is the first part of the pavement to fail. As a road’s most permeable part, this joint is susceptible to the elements. Air and water work down through this gap causing the joint to deteriorate, crack and pothole. And when the longitudinal joint fails, the rest of the road soon follows—triggering the need for even more maintenance.

How To Drive Safely This Holiday Season

The holiday season is upon us, which means sitting for prolonged periods in the car. Whether it is traveling to visit loved ones or attend a festive event, safety behind the wheel should be a priority. During the holiday season, adverse weather conditions, heightened traffic, and various distractions can call for challenges on the road. Holiday events and celebrations should be a joyous time for friends and family, but these celebrations can quickly turn into a tragic event if we are not being mindful. AAA predicts there will be 55.4 million people traveling (including more than 49 million Americans driving) between the Wednesday before Thanksgiving (November 23) and the Sunday after the holiday — making this the third-busiest Thanksgiving travel period in more than two decades. This season lets us make a commitment to road safety, the wellbeing of ourselves, our passengers, our hard-working road crews and fellow motorists.  

Here are simple ways you can stay safe on the roads this holiday season: 

  • Do not drink and drive. Do not drive when you are impaired, and do not allow your family members or friends to drive while impaired either. Designate a sober driver, call a taxi, or use a ride share service to protect yourself and others on the road. 
  • Inspect your vehicle. Take the time to ensure all of your lights are working and all fluid levels are normal. Check your tires, tire pressure, headlights, taillights, brake lights, and tag lights. 
  • Map out the route. Plan your route ahead of time and be aware of how projected weather conditions may affect your travels. 
  • Click it or ticket! Ensure you and your passengers are properly restrained in seat belts and car safety seats. 
  • Avoid fatigue. Ensure you receive a good night’s rest before driving, take breaks. If you begin to feel tired, share the driving or pull off the road to a rest area.  
  • Have an emergency plan. It is important to have a cell phone and charger with you in case of emergency situations. Keep emergency roadside assistance information on hand. 
  • Do not text and drive. Keeping your full attention on the road is important to ensure your and other motorists’ safety. If you need to use your cellphone, utilize a hands-free device. 
  • Keep a safe driving distance. A safe driving distance allows for ample time to react to traffic around you. If someone is tailgating you, allow them to pass and do not try to compete with impatient, aggressive drivers.  
  • Watch your speed. Do not go over the speed limit (especially in work zones) and give yourself plenty of time to arrive at your location. 
  • Remain calm. If you begin to feel stressed or irritable, take deep breaths and maintain your patience. If you drive with road rage, it compromises the safety of yourself and fellow drivers. 

Happy holidays, and safe travels from the AMI team!
