Correction to: Developing a Rutting Prediction Model for HMA Pavements Using the LTPP Database

Correction to: International Journal of Pavement Research and Technology https://doi.org/10.1007/s42947-023-00340-9

Dear readers,

Unfortunately, the original article was published without the author's final correction requests.

The errors identified in the manuscript pertain to the presence of both unit systems, imperial and metric. The correction now includes both systems with the metric values present between parenthesis next to the imperial one within the text and tables. This error does not affect any result or analysis present in the paper.

In this article, Tables 1, 2, 5 and 6 were misrepresented and now include both imperial and metric values. Furthermore, the following text was modified where both values are now clarified:

• In section 5.1:

“The second cluster indicates that while temperature increases within the clusters, a slight increase in the rutting values was observed. This is explained by the fact that the sections located in Arizona have thicker layer thicknesses of the asphalt layer in the range of 8-11 in (20-28 cm) compared with the other sections with an asphalt layer thickness of range of 3-5 in (7.6-12.7 cm).”

• In section 5.2:

• a. The Interstate System, having the highest classification of roadways in the United States, provides the highest level of mobility and the highest speeds over the longest uninterrupted distance. They usually have posted speeds between 55 and 75 mph (88 and 120 km/hr).

• b. Collectors are major and minor roads that connect local roads and streets with arterials. Collectors provide less mobility than arterials at lower speeds and for shorter distances. The posted speed limit on collectors is usually between 35 and 55 mph (56 and 88 km/hr).

• c. Other Arterials include freeways, multilane highways, and other important roadways that supplement the Interstate System. They connect, as directly as practicable, the Nation’s principal urbanized areas, cities, and industrial centers. Land access is limited. Posted speed limits on arterials usually range between 50 and 70 mph (80 and 112 km/hr).

• d. Local roads provide limited mobility and are the primary access to residential areas, businesses, farms, and other local areas. Local roads, with posted speed limits usually between 20 and 45 mph (32 and 72 km/hr), are the majority of roads in the U.S.

• In section 5.5.1:

“For 19 of the 24 GPS sites, the predicted rut depth was within 0.2 in (5 mm) of the measured rut depth.”

This misunderstanding has since been adjusted to ease the reading and understanding of the reader.

Please excuse this error.
