SPT Rumble Strip Contracting
SPT is the nation's largest contractor for shoulder and centerline rumble strips. SPT has cut over 50,000 miles of shoulder rumble
strips in every state combating drift-off highway crashes.
The reason our competitors have only a fraction of our experience is simple -- they haven't been competitive. Our customers know that
when you factor in our production, uncontested reliability, and tens of thousands of miles in cutting experience, SPT always offers the
lowest cost option.
Rumble strips are often the final item on your construction schedule. Installation time must be fast, accurate and reliable.
Nobody in the industry can meet these requirements like SPT.

As leader in the industry, SPT's quality control is unmatched. We staff every crew with a quality assurance foreman that immediately radios our operator to adjust for any change in conditions affecting cut quality. In every state, we have worked closely with highway offices to promote the highest standards for rumble strip specifications. We know our reputation rests with meeting those standards on every cut. |

With the high cost of downtime, NOISEPRINT's reliability is a proven
asset. Because NOISEPRINT controls the movement of the milling
head with electronic data, it eliminates the extraordinary
stress on moving parts that can cause excessive downtime on
modified rotomills or similar equipment. In the rare occasion
that a replacement part is not on-site, SPT airships the part
directly to the job -- often within hours of the order.
If necessary, SPT can supply additional mills to your project
for immediate back-up or early completion. This commitment,
combined with refined technology, has kept the downtime on
NOISEPRINT mills to less than 1% of total operational hours
nationwide.
