Pyrenae acoge la reseña de una obra divulgativa, que debe ser valorada dentro de ese género. No obstante, su lectura también será útil para cualquier profesional que quiera abrir una cata en el estado de la arqueología peninsular de finales de la primera década del siglo XXI, puesto que la firma un doctor en la materia y no un divulgador procedente de otro campo. El arqueólogo enamorado va precedido de un prólogo escrito con amor por Carmen Rigalt, periodista y madre del autor. Bajo el subtítulo Historia oculta de la arqueología española: de los hallazgos fortuitos a los falsificadores de tesoros, se plantea un proyecto elogiable, que aspira a ofrecer un panorama completo del pasado hispánico, desde la más remota prehistoria a los visigodos, haciendo cuadrar, de forma bastante equilibrada, la amplia geografía peninsular en 14 capítulos y una introducción.

Discarded tires have become a major disposal problem in the U.S. Different techniques of recycling these discarded tires have been tried. The state of Iowa is currently evaluating the use of discarded tires ground into crumb rubber and blending it with asphalt to make asphalt rubber cement (ARC}. This was the sixth project this process has been used in. This project is located on US 169 from the east junction of IA 175 west and north to US 20. Only the binder course was placed this year with the surface course to be let at a later date. There are four test sections, two sections with conventional mixtures and two with ARC mixtures.

Ten miles of U.S. Highway 20 in Webster County began to show deterioration in 1990. Any deterioration was unexpected, since the road was just constructed in 1986 and 1987. The deterioration looked much like the staining and cracking of D-cracking. Cracking was found on 391 joints throughout the 10 mile four lane divided highway. Evaluation of cores from the project reveal low air contents at those locations where cracking is occurring. The cause of the low air contents can only be speculated on. A possible cause may be the vibration from the paver coupled with the additional vibration at the joints. Other projects constructed in 1986 and 1987 with the same equipment show no signs of distress.
